90+....coral devastation.
Zoas are doing great though.....and candy canes have rebounded. Other corals are gone, some have partial heads.
This happened to me last Christmas Day. Temperature controller freaked out. Thought I had lost everything, but in a few days my green star polyp came back, and after about a month my frogspawn started to grow back. Both are doing great now. It can't hurt to give them a bit of time. They may surprise you. Good luck.
